Sleep in JavaScript - delay between actions
javascript, sleep
Solution
You can use `setTimeout` to achieve a similar effect:
var a = 1 + 3;
var b;
setTimeout(function() {
b = a + 4;
}, (3 * 1000));
This doesn't really 'sleep' JavaScript—it just executes the function passed to `setTimeout` after a certain duration (specified in milliseconds). Although it is possible to write a sleep function for JavaScript, it's best to use `setTimeout` if possible as it doesn't freeze everything during the sleep period.
Problem
Is there a way I can do a sleep in JavaScript before it carries out another action? Example: ``` var a = 1 + 3; // Sleep 3 seconds before the next action here. var b = a + 4; ```
